- the program could also be a device driver program for other printer models. In this event, the printer 5 could be configured to process commands and data output by the printer driver execution unit 45 b for a different model of printer.
- the host computer 1 also has a host display unit 46 for displaying information, a host input unit 47 for detecting operation of the connected input devices, a host storage unit 48 for storing data, and a communication interface 49 for communicating with the printer 5 .

- the host computer 1 is described generating print commands and print data for printing labels containing a barcode.
- the printer driver execution unit 45 b When the application execution unit 45 a instructs printing an image including a barcode, the printer driver execution unit 45 b generates print data including the barcode and print commands for printing.

- Examples of print media used in this embodiment include plain paper, fanfold paper, plain paper labels, fine paper labels, plastic label paper, and glossy label paper.
- the printing surface of plain paper and plain paper labels is plain paper.
- Fine paper and fine paper labels are typically fanfold paper with ink absorbency and fastness characteristics suited to inkjet printing.
- Plastic label paper is label paper made with a plastic sheet.
- Glossy label paper is label paper made with glossy paper that offers excellent ink absorbency, fastness, and chromogenicity, and retains its glossy finish after absorbing ink.
- the printer 5 has a printer control unit 27 (print control unit, acquisition unit) that controls other parts of the printer 5 .
- the printer control unit 27 includes a CPU as an operating unit, ROM and RAM. Firmware that can be executed by the CPU and nonvolatile data related to the firmware is in the ROM of the printer control unit 27 . Data related to the firmware run by the CPU is also temporarily stored in RAM.
- the printer control unit 27 may also have other peripheral circuits.
- a paper feed motor 36 printer display unit 39 , printer input unit 40 , communication interface 41 , black mark sensor 42 , and printer storage unit 50 are also connected to the printer control unit 27 .
- the printer display unit 39 has multiple LEDs or an LCD panel, and displays the operating status of the printer 5 as controlled by the printer control unit 27 .
- the printer input unit 40 includes various switches, and outputs signals corresponding to the operation of the switches to the printer control unit 27 .
- the communication interface 41 is connected to the host computer 1 .
- a black mark sensor 42 is an optical sensor disposed to the conveyance path through which the print medium (label paper or roll paper) is conveyed inside the printer 5 , and optically reads the black marks (not shown in the figure) formed on the print medium for positioning.
- the communication interface 41 (interface) communicates with the host computer 1 according to a specific protocol as controlled by the printer control unit 27 .
- the paper feed motor 36 turns the conveyance rollers (not shown in the figure) as controlled by the printer control unit 27 to convey the label paper 14 .
- the paper feed motor 36 is preferably a stepper motor, and the amount and direction of rotation of the paper feed motor 36 can be controlled by the printer control unit 27 .
- the black mark sensor 42 detects the black marks while the label paper 14 is being conveyed, and outputs the sensor values to the printer control unit 27 .
- Function blocks of the printer control unit 27 include a print control unit 27 a, image processing unit 27 b, and buffer memory 27 c.
- the print control unit 27 a and image processing unit 27 b are achieved by the CPU running firmware.
- the buffer memory 27 c is a storage area reserved in RAM (not shown in the figure) of the printer control unit 27 .
- the buffer memory 27 c could be reserved in the printer storage unit 50 , or the buffer memory 27 c could be reserved in RAM externally connected to the printer control unit 27 .
- the printer storage unit 50 (storage unit, correction value storage unit) includes a nonvolatile, rewritable storage medium such as EEPROM, flash memory, or other type of semiconductor memory, or a hard disk drive, and stores data in a nonvolatile and rewriteable manner.
- the printer storage unit 50 stores programs that are executed by the printer control unit 27 , and data including font data that is processed by the printer control unit 27 .
- the print control unit 27 a prints based on the print data and print commands input from the host computer 1 through the interface 41 .
- the print control unit 27 a controls the paper feed motor 36 to convey the label paper 14 while driving the inkjet line head 12 to eject ink.
- the print control unit 27 a calls the image processing unit 27 b to process the print data input from the host computer 1 .
- the image processing unit 27 b writes the print data to the buffer memory 27 c as rasterized image data.
- the buffer memory 2 7 c is a storage area created according to the print resolution of the inkjet line head 12 and the size of the printable area of the printer 5 .
- Print data including data specifying the barcode font and character codes is output from the host computer 1 in this embodiment.
- the image processing unit 27 b reads the font data stored in the printer storage unit 50 , and writes barcode image data to the buffer memory 27 c.
- the print control unit 27 a prints the image written to the buffer memory 27 c using the inkjet line head 12 .
- the image data written to the buffer memory 27 c is rasterized image data setting print color data for each pixel in a specific number of pixels covering the printable area of the printer 5 .
- the print control unit 27 a Based on a predefined lookup table (LUT), the print control unit 27 a converts the color information for each pixel in the image data buffered to the buffer memory 27 c to the amount of each color of ink to be ejected by the inkjet line head 12 for each pixel.
- the print control unit 27 a determines the position and size of each color of ink dot formed by the inkjet line head 12 ejecting ink droplets based on the converted ink volume data, and prints.
- the host computer 1 also has a function for correcting the barcode image data written to the buffer memory 27 c.
- the print medium used by the printer 5 could be plain paper, fine paper, plain paper labels, fine paper labels, plastic labels, or glossy labels, for example.
- the surface characteristics of the printing surfaces of these media differ, particularly in the likelihood of ink bleeding.
- fine paper has excellent ink absorbency and is therefore resistant to bleeding, but plain paper and plastic labels do not have good ink absorption and ink bleeds easily. Excessive bleeding can therefore occur depending on the type of print medium when image data for a barcode written to the buffer memory 27 c is printed.
- the printed barcode will be a barcode that does not conform to the barcode standard if the bar width exceeds the standard width, or the space between bars narrows as a result of the bar width increasing. Such barcodes may not be read normally by the barcode reader.
- the image processing unit 27 b of the printer 5 therefore adjusts the barcode image in buffer memory 27 c appropriately to the type of print medium. More specifically, when printing on a print medium that is susceptible to bleeding, the bar width is reduced to compensate for the increase in the bar width due to bleeding. More specifically, the width of the bars in the image data written to the buffer memory 27 c is reduced by a number of dots.
- the process of adjusting the barcode according to the type of print medium is performed by the image processing unit 27 b according to constants and user correction values (added correction value) stored in the printer storage unit 50 .
- FIG. 2A and FIG. 2B show exemplary tables of constants and user correction values stored in the printer storage unit 50 , respectively.
- FIG. 2A shows a constants table 50 a
- FIG. 2B shows a user correction values table 50 b.
- the constants table 50 a is a table of preset constants corresponding to different types of print media used by the printer 5 .
- the constants table 50 a is stored in the printer storage unit 50 when firmware is written when the printer 5 is shipped from the factory or when the firmware is updated.
- the types of media for which constants are set in the constants table 50 a correspond to the types of print media that can be used in the printer 5 .
- a subset of constants corresponding to some of the most typical print media could also be stored instead of storing constants for all print media that can be used.
- the host computer 1 can set the types of print media using a device driver program run by the printer driver execution unit 45 b.
- Four types of print media (plain paper and plain paper labels, fine paper and fine paper labels, plastic labels, and glossy labels) are set in this embodiment, and constants are stored for each of these print media types.
- a user correction values table 50 b of correction values set by the user for specific media types is also stored in the printer storage unit 50 .
- the printer driver execution unit 45 b displays a configuration window on the host computer 1 , and the user correction values of the user correction values table 50 b are the values input through this configuration window. More specifically, a print media type is selected (specified) using a function of the printer driver execution unit 45 b running on the host computer 1 , and user correction values for the selected print media type are input through the host input unit 47 .
- the printer driver execution unit 45 b then outputs data indicating the input print media type and the user correction values to the printer 5 .
- the printer control unit 27 of the printer 5 then stores the user correction values table 50 b in the printer storage unit 50 according to the data input from the host computer 1 . The user can thereby set correction values for a desired type of print media.
- a constant set in the constants table 50 a is a value that increases or decreases the width of bars in the barcode in dot units.
- the constants in the constants table 50 a denote the number of dots a bar width is changed; positive values indicate the number of dots by which the width of a bar is increased, and negative values indicating the number of dots by which the width of a bar is decreased.
- the constant is ⁇ 2 for a media type of plain paper
- the media type is set to plain paper by the printer driver execution unit 45 b, and printing a barcode is commanded
- the printer 5 narrows the bars based on the constants table 50 a.
- the image processing unit 27 b changes the width of bars in the barcode image data written to the buffer memory 27 c based on the change specified by the constant.
- the user correction values set in the user correction values table 50 b are values that change the width of barcode bars in addition to the constants set in the constants table 50 a. Like the constants described above, these correction values indicate the increase or decrease in dots. A positive correction value indicates how many dots the width of the bar increases, and a negative value indicates the number of dots the width decreases.
- the user correction values in the user correction values table 50 b are used in conjunction with the constants in the constants table 50 a.
- a constant of ⁇ 1 is set for the media type “fine paper” in the constants table 50 a in the table shown in FIG. 2A .
- a user correction value of 2 is set for the same “fine paper” media type in the user correction values table 50 b shown in FIG. 2B .
- the image processing unit 27 b calculates the sum of the constant plus the user correction value to get the correction value to use.
- the image processing unit 27 b thus adds the user correction value from the user correction values table 50 b to the constant from the constants table 50 a to change the width of bars in a barcode.
- the constants table 50 a stores values defined by the manufacturer of the printer 5 to enable good quality printing with each type of print media that is used in the printer 5 . For example, for each type of media used in the printer 5 , a typical or recommended print medium is selected and a constant is set so that a desirable barcode can be printed using that print medium.
- the user does not necessarily use the print medium recommended by the manufacturer, and the print condition of barcodes printed based on the set constant is not necessarily the best even when the type of print medium is appropriately selected.
- the user can set a user correction value that further corrects the constant.
- a user correction value can be set for each type of print medium, and the corresponding user correction value is automatically applied when the printer driver execution unit 45 b selects the type of print medium for printing. In other words, there is no need to manually set the user correction value in every print job.
- FIG. 3 is a flow chart showing the operation of the printing system 8 when setting a user correction value, column (A) showing the operation of the host computer 1 , and (B) the operation of the printer 5 .
- the host computer 1 In response to operation of an input device connected to the host input unit 47 , the host computer 1 first displays a window for inputting a user correction value by a function of the printer driver execution unit 45 b (step SA 1 ). Next, the type of print medium is selected, and the user correction value corresponding to the selected print medium type is input, through the displayed window (step SA 2 ). The printer driver execution unit 45 b then relationally outputs the selected print medium type and input user correction value to the printer 5 (step SA 3 ).
- the printer control unit 27 of the printer 5 then acquires the print medium type and user correction value output by the host computer 1 (step SB 1 ). Next, the printer control unit 27 sets the acquired print medium type and user correction value in the user correction values table 50 b (step SB 2 ). The printer control unit 27 stores the user correction values table 50 b in which setting the user correction value was completed in the printer storage unit 50 , or updates the user correction values table 50 b stored in the printer storage unit 50 accordingly (step SB 3 ).
- This operation enables easily inputting and setting a user correction value corresponding to a particular type of print medium based on operations performed on the host computer 1 .
- a user correction value can also be changed by the same simple operation. Because the user correction value input and set in this operation is used later when printing, barcodes can be printed easily and desirably by previously setting the user correction values.
- FIG. 4 is a flow chart showing the operation of the printing system 8 when setting a user correction value, column (A) showing the operation of the host computer 1 (SA 11 to SA 13 ), and (B) showing the operation of the printer 5 (step SB 11 to SB 15 ). Note that the operation shown in FIG. 4 can obviously be executed continuously to the operation shown in FIG. 3 .
- the application execution unit 45 a of the host computer 1 generates information related to an image containing a barcode, and outputs to the printer driver execution unit 45 b (step SA 11 ). Based on the information input from the application execution unit 45 a, the printer driver execution unit 45 b generates print data and commands instructing printing the image (step SA 12 ), and sends the print data and commands to the printer 5 (step SA 13 ). In addition to a command instructing printing, the printer driver execution unit 45 b generates a command specifying the print medium type set by operation of the application execution unit 45 a or operation of the printer driver execution unit 45 b. The type of print medium may also be set by default. In this event, the printer driver execution unit 45 b generates a command specifying the default print medium type if the type of print medium is not specifically set otherwise.
- the printer control unit 27 of the printer 5 receives the commands and print data sent by the host computer 1 (step SB 11 ).
- the image processing unit 27 b then acquires the barcode font and writes image data including the barcode to the buffer memory 2 7 c based on the received commands and print data (step SB 12 ).
- the image processing unit 27 b references the constants table 50 a and user correction values table 50 b, and acquires the constant and the user correction value corresponding to the specific type of print medium (step SB 13 ). The image processing unit 27 b then applies correction based on the constant and user correction value to the barcode image written to buffer memory 27 c (step SB 14 ).
- the print control unit 27 a converts the image data in the buffer memory 27 c to ink volume information for the inkjet line head 12 based on the lookup table, and drives the inkjet line head 12 and paper feed motor 36 to print (step SB 15 ).
- the printer 5 has an inkjet line head 12 that prints barcodes on print media.
- the printer 5 also has a printer storage unit 50 and a printer control unit 27 .
- the printer storage unit 50 stores a constants table 50 a of constants preset for particular types of recording media for adjusting how barcodes are printed.
- the printer control unit 27 then prints barcodes with the inkjet line head 12 based on the constants stored in the printer storage unit 50 .
- the printer control unit 27 also gets the user correction value input for a specific type of print medium, and stores the user correction value relationally to the specified print medium type in the printer storage unit 50 .
- the printer control unit 27 then prints barcodes with the inkjet line head 12 based on the user correction value stored in the printer storage unit 50 in conjunction with the constant stored in the printer storage unit 50 .
- barcode printing is adjusted according to a constant previously stored for a particular type of print medium, and correction based on the constant can be complemented by further correcting barcode printing based on the user correction value.
- barcodes can be desirably printed by a simple operation when barcodes can be printed appropriately to the print medium by adjusting printing based on the constant.
- barcodes cannot be printed appropriately to the print medium using correction based only on the constant, and printing barcodes more desirably is preferred, further correction is possible based on the user correction value.
- barcodes can be printed appropriately to the print medium by means of a simple, easy operation.
- the constant is a value that specifies the change in the width of the bars of a barcode printed by the inkjet line head 12 .
- the printer 5 can therefore adjust the width of the bars of the barcode based on a constant previously stored for each type of print medium, and barcodes conforming to a barcode standard can be printed using an inkjet printer 5 .
- the user correction value is also a value specifying change in the width of the bars of a barcode printed by an inkjet line head 12 . How the width of the bars of the barcode is adjusted can therefore be easily changed by specifying a user correction value, and barcodes can be printed appropriately to the print medium. Furthermore, because the printer control unit 27 calculates the actual correction value from the constant and the user correction value to print barcodes with the inkjet line head 12 , correction reflecting both the constant and user correction value can be easily applied, and barcodes can be printed desirably.
- the printer storage unit 50 stores constants relationally to plural predetermined types of print media.
- the printer control unit 27 prints barcodes based on both the constant and the user correction value relationally stored for the type of selected print medium. Printing reflecting correction based on the constant and correction based on the user correction value is therefore possible. As a result, identifying the type of print medium by the user can therefore be simplified, and the appropriate constant can be easily selected.
- the printer 5 also has an interface 41 connected to the host computer 1 .
- the printer control unit 27 prints the barcodes based on the combined constant and user correction value relationally stored for the input type of print medium. Therefore, when the type of print medium is specified by the host computer 1 , barcodes can be printed appropriately to the specified print medium type.
- the foregoing embodiment describes using a constant and a user correction value that change the width of bars in the barcode in dot units.
- Some embodiments of the invention are not so limited, however, and these could be values that change how much ink is used, the ink droplet landing position, the size of the ink droplets, or other parameter used to print the bars of a barcode.
- the foregoing embodiment also describes setting a constant and user correction value corresponding to the same type of media in the constants table 50 a and user correction values table 50 b.
- Some embodiments of the invention is not so limited, however, and the number of media types in the user correction values table 50 b could be fewer than the media types in the constants table 50 a.
- the foregoing embodiment also uses printing linear barcodes composed of bars and spaces based on a known standard such as JAN code, EAN, UPC code, ITF code, CODE39, CODE128, or NW-7, but some embodiments of the invention are not so limited.
- some embodiments of the invention can also be used for printing QRTM codes and other two-dimensional symbol codes.
- a constant and user correction value that correct the printed size of the colored printed parts can be used to accommodate ink bleeding.
- the foregoing embodiment describes an inkjet printer that uses four colors of ink, cyan, magenta, yellow, and black, but some embodiments of the invention can obviously also be applied to printers that use only black ink or printers that use two colors of ink such as red and black, for example.
- the function blocks shown in FIG. 1 can be achieved by the cooperation of hardware and software, and do not suggest a specific hardware configuration. Functions of the host computer 1 and printer 5 could also be rendered by other devices externally connected thereto. The host computer 1 and printer 5 can also operate as described above by running programs stored on an externally connected storage medium.
